Abstract
The effect of treatment of specimens of St3 steel base metal and welded joints with pulses of electric current on peculiarities of formation of macroplastic deformations in the joints subjected to uniaxial tension has been studied. An experimental procedure has been developed, which is used to investigate the mechanism of formation of L uders lines in uniaxial tension under the electrodynamic impact conditions. It is established that the characteristic simultaneous formation of plastic deformations induced by welding and current impact takes place in electrodynamic treatment of welded joints on steel St3.
Keywords: electrodynamic treatment, plastic deformations, low-carbon steel, Luders lines, uniaxial tension, residual welding stresses, butt joint, flat blade-shaped specimen
